I'm working on a project requires integration between Salesforce and Microsoft Navision with NTLM authentication.

As I see people refer to NTLM authencation implementation ApexNTLM but it doesn't work for me. I get 401 status code.

The credentials are valid because I'm able to get proper results with browser, SOAP UI and Insomnia (Postman's NTLM authentication is broken).

So, I'm looking a way to handle this issue. Any help would be much appreciated.

Thanks (+100 Bounty Points added)

  • Are you doing it via delegated authentication? – David Brossard Sep 19 at 1:33
  • Hi David, not via delegated auth. – Fırat Esmer Sep 20 at 9:23
  • I think I had misunderstood your post. What you're doing it's trying to integrate with a service that uses NTLM auth, right? – David Brossard Sep 20 at 15:40

    Hi David. Yes, I'm trying to integrate with Microsoft Navision OData REST service based on NTLM authentication. – Fırat Esmer Sep 20 at 16:16
  • @FıratEsmer This seems to be a similar issue reported on the github repo. did you try to contact the contributors of the repo ? – Shamina Sep 26 at 11:08
